Yep, we totally hijacked this page! We’ve been using RV Digest-It Ultra on every single adventure. It’s one of those products that actually works, and once we started using it, it became a non-negotiable part of our RV routine.
RV Digest-It Ultra comes in two easy options: a concentrated liquid or our ultra-convenient Stick Packs. Both deliver the exact same powerful bacteria and enzyme formula — the only difference is how you use them. The liquid is perfect for traditional dosing, while Stick Packs are pre-measured, mess-free, and made for grab-and-go RV life. No matter which you choose, you’re getting the same waste-digesting, odor-eliminating performance every time.
RV Digest-It Ultra uses a powerful blend of bacteria and enzymes to liquify solid waste and all brands of toilet paper (even brands you didn’t think were possible to digest!) That means:
Instead of just covering up smells, this product eliminates odors by digesting the waste that causes the stink in the first place. Then we came along and gave it the Grateful Glamper glow-up with our exclusive Watermelon Smash scent!
Tank sensors are critical and expensive to replace. RV Digest-It Ultra helps keep sensor probes clean so you’re not second-guessing your tank level on the road.
Foul smelling odors from your black or gray tank can quickly turn the RV trip of a lifetime into a nightmare. Solve these problems with RV Digest-It Ultra.
Many holding tank treatments fail to break down solids and paper, leaving you with clogs and residual waste. Solve holding tank waste buildup with RV Digest-It Ultra.
For most people, the black tank comes to mind first when they think about RV tank odors, but the gray tank can smell too! Solve gray tank odors with RV Digest-It Ultra.
RV Digest-It Ultra is powered by bacteria and enzymes, the gold standard of holding tank treatment ingredients. Why are they the gold standard? Though there are many different types of holding tank treatments available, only those powered by bacteria and enzymes are capable of doing ALL of the things necessary inside an RV holding tank: odor elimination, solid waste breakdown, and sensor probe maintenance. Other treatments can usually do ONE of these things, but only bacteria and enzymes can do them all with the most guaranteed success.
There are a few things that can inhibit the success of RV Digest-It Ultra, so take note that you don’t do these things as they will reduce the effectiveness of RV Digest-It Ultra:
Bacteria and enzymes are living organisms and must remain hydrated to survive. If you use too little water, you will dehydrate the bacteria and they won’t be able to do their job of odor elimination and waste digestion.
Be sure to hold your flush pedal down for 10 FULL SECONDS every time you flush your toilet.
Another issue that sufficient water solves is “the porta potty effect.” This is when your poop and paper form into a mountain and stick out above the water line due to insufficient amounts of water in the tank. Once poop is exposed above the water, NO holding tank treatment will be effective in eliminating the odor! Keep your poop underwater by using enough water with every flush.
How much water is going down your tank every time you flush? Watch this video to find out!
If you are using enough water with every flush, the average family of 4 should have to dump their typical 40 gallon black tank every 3-5 days. Sure, you can extend this but you are doing it at your own risk! Allowing a tank to go beyond 7 days without dumping will likely cause your tank to turn “septic.” This is when the environment inside your tank becomes ideal for anaerobic bacteria (the BAD bacteria that come from your stomach and create that all-too-familiar toilet smell) and they begin to take over and wreak havoc.
Dumping frequently enough will help solve this problem. Plan your trips around one weekly dump at minimum, or ideally dump every 3-5 days.
As we have mentioned several times, bacteria are living organisms. If you camp in temperatures that are above 95℉, you must keep the bacteria hydrated and the tanks cool. If you don't keep your tank temperatures cooler, the tanks will become septic and bad bacteria will take over. Some RVers don’t like to face this reality. They believe they have a right to camp in excessively hot climates, without adding any water (pee is not water!) to their tanks because they don’t want to break camp to go dump their tanks every week. If you are the stubborn type who insists on camping this way, please know that you cannot have your cake and eat it too. You may be able to eliminate odors with certain chemical or zinc-based holding tank treatments, but it is only a matter of time before you have clogs, waste buildup, and misreading sensors. Trust us, we’ve helped thousands of RVers solve tank problems because they insisted on camping this way, treating their tanks with these types of treatments, and they ended up paying the price. Using enough water isn’t a suggestion, it’s a requirement. Rest assured, thousands of RVer use RV Digest-It Ultra in extremely hot temperatures successfully – and you can too!
If your black tank stinks after using RV Digest-It Ultra, the answer is usually simple: use more water. The overwhelming majority of people who contact us are able to solve their issue simply by increasing the amount of water they use with each flush. See above for more information on this. Additionally, we recommend that all RVers follow The Unique Method. Following this method will eliminate 99% of all odor issues in your black tank. If you believe you are using enough water, and you are following The Unique Method, and you are still getting an odor, please contact our customer support team for assistance. This is extremely rare and there may be some other uncommon factors that are causing odors in your tank that need to be addressed.
RV Digest-It Ultra is our strongest holding tank treatment for breaking down solid waste. We mean that! If you are experiencing waste buildup inside your black tank it’s likely you are doing something that is causing that to happen.
Normally when a gray tank stinks it’s because of excessive grease buildup. Using RV Digest-It Ultra each time you go camping will help prevent this, but grease can be tricky for a number of reasons. If you find yourself getting smells from your gray tank, we suggest deep cleaning your gray tanks by following this guide.
Sometimes gray tank smells can come from sewer gasses from the campground sewer or septic system backing up into your RV. This will occasionally happen if you leave your gray tank open while camping on hook-ups. To solve this problem, keep a p-trap in your discharge hose. This guide will walk you through the steps to adding a p-trap to your discharge hose
The Unique Method is an easy-to-follow treatment method that is used by thousands of RVers every day to prevent holding tank problems before they happen. Treating your holding tanks with RV Digest-It Ultra, following The Unique Method, will ensure your holding tanks remain free from odors, clogs, and misreading sensors.
